What does it feel like to be passionate about your daily work? How do people find their way into fascinating, unusually fulfilling careers, even against the odds?  Space lawyers and bibliotherapists; euthanasia activists and women's rugby champions; shark experts and solar power visionaries; a master perfumer and a moon dust maven, among many others. What all of these people have in common is the courage to pursue their dreams and obsessions, no matter how niche or particular, and transform them into their life's work. In the process, they've enacted lasting change in the world around them.  Delving into the working lives of others for publications as diverse as newyorker.com, The Monthly and WIRED, Ceridwen Dovey's inquisitive, thoughtful approach has allowed her to explore fields of knowledge and expertise that are often inaccessible to outsiders. The resulting profiles are a celebration of the extraordinary and meaningful work done by those on paths less travelled.
